Can this bag zip to another to create a two person cocoon?
Yep! Almost all TNF bags, as well as many other manufacturers, use the same zipper for that purpose. Ideally get another TNF bag so you'll know for certain. One would have to be left hand, the other right hand zips. It wouldn't matter if the bag were regular or long, the zipper length is the same.
